AUTOMATIC LIQUID-DISPENSING DEVICE.

an apparatus which may be actuated to automatically deliver a measuredquantity of liquid, as for instance beer.

Another object is to provide such an apparatus which may be adjusted todeliver ditlerent quantities of liquid.

7 Other objects are to simplify the construction of such apparatus andprovide an apparatus efi'icient and reliable in operation. With these obects in view the invention comprises generally a dispensing nozzle orfaucet provided with a normally closed stop-cock, retaining ineaii's forretaining said stop-cock in open position during passage of liquid,releasing means, and .i'neans actuated by the flow oi liquid actuatingsaid releasing nae-ans upon passage of a pre determined quantity ofliquid.

The invention will he described more in I detail in connection with theaccompanying dii'awin s illustratin on a :5 thereof, whereinl W i 1 11-f tkn 1 0 L lguie 15 an eeiauon o it app.1ra. i with cover removed)showing one side thereof. l lg. 2- 1s avertical sec nal view of theapparatus. l 1g. 3 1s a. horizontal secembodiment tional view on line3-3 Fig. 1, Fig. 4. is a horizontal Fig. 2. p

In the drawings 5 designates the dispensing nozzle having a passage 6therethrough for the How of liquid. In" the upper part or" said nozzleand adapted to close the passage 6 is any suitable stop coclc or valve7. shown the stop-cock 7 in the'form of a slide or gate valvereciprocating in a here 8 at right angles to passage 6 and abuttingagainst a seat 9 formed in said passage. When in closed position thevalve 7 corn pletely shuts off the flow of liquid. Stopooelt 7 isactuated by a lever 1 pivotally mounted upon a pin 11 projecting from alug 3 formed uphn the device. Lever 10 is provided with an arm 13engaging within a sectional view on line H specification of LettersPatent Patented Dal-58. 3 1912 Application filed. August 26, 1910.

slot 14 in the valve 7.' The stop-cock 7 is normally retained in closedposition bya springlo, reacting against a fixed part of the structureand a projection 16 upon lever l0.- The spring, when in the form of acoiled spring, as shown, is preferably braced by a pin 17 projectingthrough its coils. The pin 1? may pass through the projection 16 at oneend and be attached to a, fixed part of the structure at its other end.

In order to hold the stopcock open, lever 10 is provided with a detent18, pivoted thereto at 18. lhe detent 18 is provided with a pin or stud19, which is adapted to be engaged by a projection 20 in a fixed part oithe s ructure. Projection 20 has a cam surl'ace 21 on its upper side.hen lever 10 is depressed to withdraw the stopcock 7 to open position,detent 18 is moved :iorward, its pin 19 riding upon cam suriu e 2.1 ofprojection 20. When, the parts reach their fully open position pin 19drops down behind projection 20 and is retained, thus holding the partsin open position. The passage! 6 now being open liquid is free chan'iberpreferably intersectii'ig passage (3. This chamber is closed on its openside by asnug-litting cap or plu 22'. In this iihan'iber is mountedwheel :23 adapted to be rotated by the flow of liquid. This Wheelpreferably has a plurality of measuring buckets around itscircumference, by which measured quantities of. liquid are passed as itrotates. The wheel is keyed to a shaft 25, passing through one side of(Zllfill'llXiI' 22h) the exterior. On the end of shaft :25 is aneccentric pin 26 or equivalent device. The eccentric pin 26 engages oneend of an arm 27, pivoted'at 28 to a fixed part of the structure. A slot28 is preferably formed in the arm for engagement of the pin. Arm 27 haspivoted thereto a weighted pawl 2.) having a tooth 30 engagin;- theteeth 31 of a toothed wheel 32 pivoted in any suitable manner upon thestructure, as for instance upon the. reduced portion of a. lug 33projecting from the device. A weighted pawl 34 having a teeth 35 alsoengages wheel 32 for the purpose of preventing hack motion of the wheelwhen actuated by pawl 29. Pawl 34. is preferably pivoted to a lug 36projecting from the device. The tail of this pawl also overhangs thetooth 30 on pawl 29 so as to be lifted when pawl 29 is liited out ofengagement predetermined amount of liquid has passed,

pin 37 on wheel 32 comes in contact with the cam surface 38 on detent18, thus gradually raising the detent. \Vhen pin 19 on detent 18 israised above the edge of projection 20 spring 15 is free to act, andretracts the detent and forces stop-cock 7 forward to close the passage6 and thereby cut oil the flow of liquid. Detent 18 is provided with anarm 40; which, when the detent is raised by pin 37 on wheel 32, comes incontact with the tail of pawl 29 and lifts it, together with pawl 34,out of engagementwith the teeth of wheel 32. Wheel 32 is returned toinitial position by any suitable means. As shown, the wheel is weightedat one side, as at 41. Substantially all of the liquid passing throughthe device is measured thereby, in-

asmuch as the raising and dropping of the detent behind its stop (andconsequent release of the ratchet wheel) in the opening operation, ismomentary, and the initial return of the ratchet wheel is sluggish, thelatter being substantially in equilibrium. Consequently when the detentlifts the actuating stop pawl from the ratchet wheel, the latter has notacquired suflicient potential force or unstability to return itmaterially before the pawls again drop into engagement with the ratchetwheel.

In order to provide for the adjustment of the apparatus to deliverdifferent quantities of liquid, there is provided an adjustable stop 42.As shown, this stop works in a slot 43 in the casing and is fixed inposition by a screw or screws 44. This stop engages with a pin orprojection 45 on wheel 32. By

lowering the stop the initial position of the wheehand consequently pin37, is advanced,

' so that wheel 32 will have to rotate a less distance before pin 37comes in contact with and releases detent 18 to shut off the flow ofliquid. The quantity of liquid may be varied by these means eitherminutely or over a wide range.

. A deflector 46 is preferably formed in passage 6 adjacent to chamber22 to direct liquid upon the tips of buckets 24, in order to give thewheel 23 a more positive action.
